Abstract :
Multi-rate methods are under development for performing time-domain simulation of EMTs in large power systems. It is affirmed in this paper that TD EMT analysis can benefit from complementary analysis in the frequency domain. It is proposed, in addition, that an important trend for frequency domain EMT analysis is the development of multi-rate methods. The first part of the paper presents the basic relations between TD and FD analysis as applied to single-step EMT analysis, while the second part describes a methodology for representing signals for EMT analysis in multi-resolution frequency domain.
